Strange Pedal Mounting Problem-Your thoughts appreciated

Loading...

Greetings,

I fixed up an MIJ kit that I now have all the hardware for. I'm still waiting on a front bass drum hoop and head, but I was anxious to get these set up and play them, as well as mark all the spaces for my stands on my rug (like I do with every kit). I figured not having a front hoop or head would not affect any of that. BTW, that's the original hoop, but the inlay was missing. This drum has some pretty major fading, almost to a midnight blue, which I actually like better. The closest I could get was Blue Glitter inlay from Precision Drum Company. I know it doesn't quite match, but I actually like the contrast between the two shades of blue, it's cool looking and unique, at least to me. Back to the task at hand:

I went to set up the kit, and as always I start with the bass drum. When I went to clamp the pedal on and get started, I had something odd happen that I have never seen before. Hopefully the pictures will help tell the story.

I set up my bass drum (no pedal) so that it's pretty level front to back. After I clamp on the pedal, I adjust the spur length as needed. I usually like the front of the bass drum off the ground a few inches, but nothing extreme. Photo 1 below shows how I started off the bass drum positioning. Pretty standard stuff. Photo 2 below shows the front of the bass drum with that same positioning. Again, very standard, no extreme or weird angles going on.

Photo 3 shows the pedal attached loose, not tightened down yet. As expected, the batter side of the bass drum is now a bit higher because of the pedal being underneath it. When I go to tighten down the pedal is where the problem starts. The pedal won't stay flat on the ground, and as the toe clamp tension increases, it lifts the back of the bass drum higher and higher off the ground, while the pedal itself raises off the ground.

Photo 4 below shows the same as photo 3, but in Photo 4 the pedal is tightened down firmly. You can already see the difference in the pedal between the two pictures. In photo 4, the pedal is tilted back at further angle, away from the head. Photo 5 shows a close up of what's happening when the pedal gets tightened down. You can clearly see that the base of the pedal directly under the hoop is off the ground and slanting backwards.

I'll continue this thread with more photos down below...................

.....................continued from above...................

When this started happening, I thought that I needed to adjust the spurs outward (make them longer) so that the front end of the bass drum would be higher and this would also, in theory, put the batter side lower to the ground.

See the final two photos below (6 & 7). All this did was make the entire drum higher off the ground, and made the pedal go even higher and at more extreme of an angle.

I tried this with 4 different pedals, including a heavy duty Tama with a solid base plate, and it happened on all four pedals. Since the solid base Tama can't "float" like the others, almost the entire pedal was in the air while attached to the hoop with the spurs in position like photo 6, only the heel section was in contact with the carpet. So weird! The batter side hoop is the original wood hoop the drums came with, a standard 1.5" wide wood hoop. It is not thicker or thinner than any other of my wood hoops. I am using a small piece of a thin mouse pad to protect the hoop where the pedal clamps to it. I know this can't be the problem, because I use this same thing on several other kits with no issues.

In all my years of setting up kits, I've never had this problem before. What could be causing it? I am puzzled!

I know that on virtually all pedal set ups, when the pedal is loose on the hoop, the linkage or drive is very close to the head. As you tighten down the toe clamp, the linkage gets further and further away from the head, but the pedal always stays firmly on the ground.

I would really appreciate your suggestions on this one. I've never been stumped like this before.

Thanks for your help!

I had a similar issue with a Slingerland Epic pedal and ended up making an angled shim out of a shingle to fix the clamping angle on the bottom plate. Something is going on with that hoop...

Looks to me that there is a decent "Flare" towards the outer edge of that hoop.

Cheers

Perhaps loosen the BD claws and spin the hoop around.

It could be that the hoop is warped on that section?

That's a weird one.

Try flattening the end of that length of flat stock joining the heel to the uprights. It looks to be curving upwards right where it gets clamped. It's plenty thick enough to lift one end of a 20" bass drum especially 3-ply MIJ. OTOH I've encountered this annoying phenomenon using a BD pedal of a completely different design...maybe just raise the front a bit, see what happens.

It's a shame simply flipping the hoops over wouldn't quite work. That'd be a nice easy fix, but putting the rounded outer side against the head would probably affect the tunability and tone etc. I can't really say because I've never done that, but that's what I imagine would happen.
